Solitary Metacarpal Osteochondroma; an Unusual Location

Although, osteochondroma is the most common bone tumor, metacarpal involvement is quite uncommon and usually accompanies multiple hereditary exostoses. Herein, we described a patient with solitary ostechondroma of the fourth metacarpal bone, and discussed the differential diagnosis of bony spurs that can be seen in hand.

Association among Orthodontic Malocclusions, Paranasal Sinuses Anatomic Variations and Adenoid Vegetation in Children Using CBCT

The aim of this study is to evaluate the relationship between orthodontic malocclusion, paranasal sinus (PS) variations, and adenoid vegetation in a group of pediatric patients with chronic rhinosinusitis. Clinical and radiographical data were retrospectively evaluated and 58 patients were diagnosed as having chronic sinus disease. Cone-beam computed tomography (CBCT) images were acquired with Newtom-3G. Anatomical variations of the PS were assessed on every section. Additionally, for cephalometric analysis, the images were imported into the InVivoDental software program. A total of 252 anatomical variations, which encompassed 19 different types, were detected in the current study. Concha bullosa was the most common anatomical variation, at 72.4%. Septum deviation was the second most common one, at 67.2%. The Class III group exhibited a significantly higher prevalence of concha bullosa and secondary middle turbinate than the other groups. While adenoid vegetation was most common in the Class III group, sinusitis and antral disease were most common in the Class II group. Overall, Class III subjects exhibited fewer PS variations. In conclusion, concha bullosa emerged as the most prevalent anatomical variation, with distinctive patterns observed across different malocclusion groups. Therefore, CBCT is useful, especially in pediatric patients, due to its low dose advantage

LYME ARTHRITIS IN PRIMARY CARE; CASE REPORT

Primary health care is the closest point to the patient. The person who is ill or suspicious of his / her health goes to the family physician, the family health center or the closest health institution. The correct diagnosis and treatment at Primary health care center is of great importance in terms of the cost effectiveness and public health improvement

Pathological staging of muscle invasive bladder cancer: is substaging of pT2 tumors really necessary?

OBJECTIVE: Compare clinical outcomes in patients having urothelial tumors invading less than one half of the depth of bladder muscle and greater than one half of bladder muscle and, to determine various clinical variables as predictive factors for survival. MATERIALS AND METHODS: According to our inclusion criteria, 57 patients among cases with T2 bladder tumor were selected. Thirty-five patients (61.4 %) had pT2a (Group-1) and 22 patients (38.6%) had pT2b (Group-2) muscle invasive tumors. Mean follow up time was 7.3 years for Group-1, and 6.1 years for Group-2. Multivariate analysis was performed in order to identify possible correlation of clinical variables like age, gender, grade of primary tumor, appearance of local and/ or distant metastasis with patient outcome. RESULTS: Five year recurrence-free and overall survival rates were 69.1% and 44.3% for patients with pT2a tumor, whereas these ratios were 66.1% and 43%, respectively for patients with pT2b tumor (p = 0.896; p = 0.975). Mean overall and progression-free survival times were 87.7 ± 13.8 and 116 ± 13.12 months for Group-1, while they were 73.8 ± 13.7 and 88.85 ± 12.55 months for Group-2, respectively. On both univariate and multivariate analysis, age was noticed as an independent predictive factor for survival. CONCLUSIONS: The depth of muscle invasion in bladder tumors has no prognostic significance. Recurrence of the disease either locally or at distant sites dramatically shortens patients' life. Being older than 60 years old during the time of radical surgery, is also a bad prognostic factor for overall and progression-free survival

Effect of glucosamine chondroitine sulphate on repaired tenotomized rat Achilles tendons

WOS: 000293815300009PubMed: 21762066Objectives: We evaluated the effects of glucosamine chondroitine sulphate (glcN-CS) on rat Achilles tendons in this experimental animal study. Materials and methods: Thirty Wistar albino type rats weighing 300-350 g were randomly grouped into two. Group A: Achilles tendons were tenotomized, repaired and, glcN-CS given orally. Group B: Achilles tendons were tenotomized and repaired. All the rats were fed with pellet chow. Five rats in each group were sacrificed at 4, 8, and 12 weeks interval. Tensile strength of three tendon specimen from each group were tested biomechanically and two specimen were analysed histopathologically via immunohistochemical staining and hematoxylin and eosin staining. Contralateral side Achilles tendons were also grouped and analyzed as controls (group C and D). Results: Histological results showed well organized collagen formation and less inflammation in group A. Biomechanical testing showed higher tendon strength in group A at eight weeks which is not statisticaly significant (55.3 +/- 4.84N, p=0.078). Rats which were were given glcN-CS had greater tendon strength which is statisticaly significant (50.01 +/- 5.62, p=0.014). Conclusion: Glucoseamine chondroitine sulphate improved results of Achilles tendon healing in rats. This result might be due to decreased inflammation and stimulation of collagen synthesis. Although glcN-CS is recommended only in osteoarthritic patients to relieve symptoms and signs it can also be prefered in treatment of soft tissue injuries formed during sports activities

Evaluation of articular eminence pneumatization using cone beam computed tomography

Aim. Knowledge about the anatomy of the temporomandibular joint (TMJ) and its surrounding structures is mandatory for success in surgical interventions and for understanding the pathway of spread of infections in this region. This study aims to investigate the anatomy and morphology of pneumatized articular eminence (PAT) using cone beam computed tomography (CBCT) imaging in a group of patients. Methods. A retrospective study on 825 patients (377 males, 448 females) aged between 18 and 91 years was performed using sagittal and coronal CBCT images. PAT was defined as non-expansile, nondestructive cyst-like radiolucency in the zygomatic process of the temporal bone, which appears similar to the mastoid air cells. It was classified in two groups as unilocular and multilocular. Statistical comparison of gender, age and localization was performed using chi-square test and correspondence analysis. P0.05). Conclusion. Pneumatization of the articular eminence is a challenging entity for TMJ surgery and spread of infections in this region. Practitioners who are dealing with TMJ surgery and pathology should have detailed information about this anatomical variation since it may cause serious complications
